The experimental manipulation of mortality salience (MS) represents one of the most widely used methodological procedures in social psychology, having been employed by terror management researchers in hundreds of studies over the last 20 years. One of the more provocative conclusions regarding this task is that it does not produce any reliable changes in self-reported affect, a view that we refer to as the affect-free claim. After reviewing 336 published studies that used the standard version of the MS task, we suggest that the evidence on which this claim is based may be less definitive than is commonly supposed. Moreover, we propose that the MS manipulation can, in fact, produce significant and meaningful changes in affect once one employs the appropriate measures and experimental design. In support of this position, we report 4 experiments, each of which demonstrates reliable activation of negative affect, especially with respect to fear-/terror-related sentiments. We discuss the implications of our findings for terror management theory as well as for research and theory on the measurement of mood and emotion.

Products containing per- and polyfluoroalkyl substances (PFAS) have been used for decades in industrial and consumer products. These compounds are persistent in the environment, bioaccumulative, and some are toxic to humans and other animals. Since the early 2000s, laws, policies, and regulations have been implemented to reduce the prevalence of PFAS in the environment and exposures to PFAS. We conducted a scoping literature review to identify how PFAS are regulated internationally, at the U.S. national level, and at the U.S. state level, as well as drivers of and challenges to implementing PFAS regulations in the U.S. This review captured peer-reviewed scientific literature (e.g., PubMed), grey literature databases (e.g., SciTech Premium Collection), Google searches, and targeted websites (e.g., state health department websites). We identified 454 relevant documents, of which 61 discussed the non-U.S. PFAS policy, 214 discussed the U.S. national-level PFAS policy, and 181 discussed the U.S. state-level PFAS policy. The drivers of and challenges to PFAS regulation were identified through qualitative analysis. The drivers of PFAS policy identified were political support for regulation, social awareness of PFAS, economic resource availability, and compelling scientific evidence. The challenges to implementing PFAS regulations were political limitations, economic challenges, unclear scientific evidence, and practical challenges. The implications for PFAS policy makers and other stakeholders are discussed.
